GRAIN-BINDER.

SPECIFICATION formingpart of Letters Patent No. 282,335, dated July 31, 1883. Application tiled September 23, 18852. (No model.)

To all whom it may concern.'

Be it known that I, CHRISTOPHER W. Lnj States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Grain-Binders, of which the following is a specication, reference being had therein to the accompanying drawings.

The object of this invention is to provide means through which to adjust the throw or traverse of the needle or binder-arm in order to insure that it shall properly present the cord to the knotting mechanism; and it consists in combining with the needle, its pivot, and its actuating-arm an adjustable mechanism, as will b e hereinafter described.

In the drawings I have illustrated two constructions which I have adopted for carrying out my invention.`

Figure lisan elevation of so much of a grain-binder as is necessary to show this invention, the needle being in the position which l it occupies while the knot is being tied. Fig. 25.

2 is a detached view, partly in section, of a portion of the needle, its shaft, and connecting devices. Fig. 3 is a side view of the same parts. Figs. 4. and.5 show detached views of devices for adjustably connecting the cogged segment to the needle-pivot or shaft end.

The general construction of a machine to which I have applied this invention is shown and described in my Patent No. 226,865, April 27 ,e 1880, and need not therefore be given in detail here; but, for convenience, I will use the letters of reference which in that patent e are applied to corresponding parts.

In the drawings, G3 is a crank-arm upon the forward end of a shaft, G2, and having a crankpin, G, provided with a friction-roller.

H is a bell-crank lever pivoted to the frame above the shaft G2. The lower arm of the lever is provided with a peculiar curvilinear slot, hX, in which the crank-pin G4 reciprocates, Y

being facilitated in its movements by the friction-roller. The upper arm of the bell-crank lever H is pivoted toa link, It, which in turn is pivoted to an arm, h, of the needle-frame.

I is a bar or rod pivoted to the crank-pin G4, carrying at its .upper end a cogged rack, i, which meshes with a spur-segment, I.

' needle.

I2 is a guide-frame (carrying a friction-roller) segment I', so as to be in constant mesh therewith, whatever be the position of said segment. This guide-frame is supported by an arm, i', carrying at its lower end a sleeve or eye, i2, through which the bar or rod I passes, and which permits the bar I and the arm t" to reciprocate relative to eachother. The segment I is adjustably secured to a shaft, K, whichis mounted in a sleeve, K, which is supported upon an oscillating frame. K3 is an upright or bracket carrying on its inner side the arm 7L', to which the link h is pivoted, as above described, and at the top supporting the sleeve or shaft-support K.

L is the binder-arm or needle adjustably secured to the shaft K. Near its outer or point end it is provided with the usual eye and cordpulley. The needle or arm L and the seg-mentgear I are both secured to the shaft K in such manner that any wear or lost motion may be compensated for by the attaching device. In practice I prefer that both the needle-arm and the segment-gear shall be adjustably attached to the shaftK; but I may operate the machine satisfactorily even though only one of them be thus mounted on the shaft, as will be hereinafter fully explained.

Referring to Figs. 2 and 3, K4 is a hub keyed rigidly to shaft K in close proximity to the K5 is a T-shaped arm cast in one piece with the hub K4, and provided at its ends with angular extensions or arms, which extend on lines substantially parallel with the shaft K across the plane of the needle, at which points they are provided with set-screws 7c, the inner ends of which engage with opposite sides of the needle, by which/its position (relative to shaft K) may be gradually adjusted.

In Figs. aand 5, K6 is a similar hub, keyed to shaft K, and provided with substantially radial arms, which have angular extensions at their outer ends, these extensions intersecting the plane of the toothed segment I-, and carrying set-screws k, the inner ends of which engage with the segment on opposite sides of the shaft, whereby the said toothed segment may be adjusted relative to the shaft K by rotating it slightly in either direction upon said shaft. Thus it will be seen that by the use of IOO the devices shown in these two figures, 4 and 5, the throw of the needle relative to the movement of the crank G3 may be regulated at will.

It will of course be understood that when the devices shown in Figs. 4 and 5 are employed, the needle may b'e keyed or otherwise attached firmly to shaft K, and that when the devices shown in Figs. 2 and 3 are employed,

those used for adjusting the sector shown inV Figs. 4L and 5 may be dispensed with, the toothed sector being attached rmly to shaft K.

It will also be seen that the hub Kt, its T- shaped arm, and set-screws constitute a supplemental driving-arm, which may be made of any desired strength and keyed fast to the shaft K, and that by reason of the set-screws being supported at some distance from thev shaft the needle can be adjusted with much greater accuracy and facility than if the adjustment were effected by means of keys or similar devices within the hub of the needle.

It will also be seen that my device has marked advantages as a carrier for the needle ences are liable to occur during the process 'of casting.

I do not in this case desire to claim any inventions except those which are specifically recited in the claims hereof, reserving to myself the right to claim all other patentable features herein shown or described in another application heretofore filed by me, and of which this is a division.

What I claim is- 1. In a grain binder, a needle mounted loosely upon its shaft, in combination with a driver rigidly attached to said shaft, and an adjustable device for clamping the needle to the driver, substantially as set forth.

2. In a grain binder, a needle mounted loosely upon its actuating-shaft, in combination with an adjusting mechanism rigidly attached to said shaft, whereby the needle may be adjusted by oscillating upon its shaft, substantially as set forth.

8. In a grain-binder, the combination' of the needle-shaft K, the needle, the hub K", the T- shaped arm K5, and the set-screws, substantially as set forth.

In testimony whereof I affix my si gnature in presence of two witnesses.
